JOSEPH BENNOR, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR or o E- HALF OF HIS RIGHT To JOHN N. MOLEAN.

IMPROVEMENT IN EXTENSlQN TABLES FOR SEWING-MACHINES.

Specification forming part of Letters Patent No. 136,959, dated March 18, 1873.

To all whom it may concern.-

Be it known that I, JOSEPH BENNOR, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain Improvements in Extension Tables for Sewing-Machines, of which the following is a specification, reference being had to the accom panying drawing.

My invention consists in a novel arrangement of devices for attaching a sewing-machine oover to the end of the table, so as to form an extension or continuation of the top thereof.

Figure 1 is an end view of a sewing-machine table provided with my devices; Fig. 2, a side elevation of the table with the cover attachedto its end; Fig. 3, a perspective view of the cover; Fig. 4, an under view of the table top.

In carrying out my invention I construct the table and the cover in the ordinary man- 11 er, and provide them with a suitable arrangement of devices by which the cover may be firmly connected to the end of the table soas to be flush with its top and form an extension or continuation thereof.

A represents the table, and B atrod, mounted lengthwise under its top in such manner that it can both turn and slide endwise. The outer end of the rod is supported in a notch in the top of one of the iron legs of the table, while the inner end is supported in a block, 6, secured to the under side of the table top. The rod is provided at its outer end with a hook, g, and a depending arm, h, and at its inner end with two studs, k and l, situated on opposite sides of the block 0, which is provided with notches m and n for them to lock into. When the cover is to be attached the arm h of the rod is turned down and then the rod drawn outward so as to look its stud 7c in the notch n, as shown in Fig. 2, by which the rod is held so that it can neither turn nor slide further outward. The cover, which is provided with an eye-plate, 0, in its side, is then hooked on the end of the rod B, and its side permitted to rest against the end of arm h,

oint where the cover and table join each other.

When the extension is no longer required the top is unhooked and removed, and then the rod pushed inward sufficiently to unlock the stud k, the arm b turned up against the under side of the top, and the rod pushed inward until the stud 1 looks into the notch we so as to hold the arm up out of the way and out of sight.

Having thus described my invention, what I claim, is

In combination with the sewing-machine table, provided with the notched block 6, the rod B, provided at its inner end with the studs m and n, and at its outer end with the hook g and arm h, when arranged as described, for the purpose oflocking the cover to the end of the table, as set fort JOSEPH BENNOR.
